BUILDING I CONSTRUCTION Filed May 22, 19 12 2 Sheets-Sheet 2 INVENTUR BY N ATTORNEY Patented Oct. 10, 1944 BUILDING CONSTRUCTION Everett H. Fuller, East Walpole, Mass, assignor to Bird & Son,-inc., East Walpole, Mass., a corporation of Massachusetts Application May 22, 1942, Serial No. 444,055

2 Claims.

building walls provided with ornamental siding strips of a type known to the art, one type thereof being formed with wide and narrow areas of diiferently colored adhesively aflixed mineral Cir granules giving a visual appearance of alternate I areas of .brick or stone and mortar or wood; and these corner elements are especially designed to carry out the brick, stone or wood imitation at the junctur of said walls. It is the purpose to include in the scope of this invention, both the mineral granule surfaced type of mortar line, and that in which the mortar line is burned or branded into the mineral granule covered asphalt coating.

For the purposes of simplification and economy, the corner element of this invention may be formed with a base which is composed of flbreboard and is so constructed and reinforced that the element maintains its preformed angular configuration adapting it for application to the corner of a building, and yet possesses a certain amount of flexibility, due to the absence of any metallic reinforcement, permitting the unit to conform more readily with building irregularities. I

-In the accompanying drawings, the corner element is shown as a brick and mortar cap sheet type element applied to a wall construction having brick and mortar appearingsiding strips.

Figs. 3 and 3a are diagrammatic representations illustrating certain of the steps involved in one method of assembling the corner element;

Fig. 4 is a perspective view of a single outside comer element broken in the middle to indicate variable length Fig. 5 is apartial view of an outside corner element showing parts adapted to interfit with parts of the corner element of Fig. 4 to provide hrough a vertical series of comer elements provided with a waterproof joint;

Figs. 6 and '7 are fragmentary vertical sections along the lines 8-8 and 1-1, respectively, of Figs. 4 and 5; i

Fig. 8 is a vertical section of the construction taken generally along the line 8-8 of Fig. 1, but including an additional lower corner element; and

Fig. 9 is a diagrammatic representation similar to Fig. 3a, but illustrating a modified form of the invention providing a corner element adapted for use in inside corner construction.

As shown in Fig. 1, the wooden wallboards 2. forming a building juncture at an upright corner stud 4, are covered with imitation brick wall siding strips 6, which meet at the juncture as shown in Fig. 2. The siding strips are capped at the corner by flxng thereover the corner element 8 of this invention, preferably by nailing.

The corner element 8 is shown more in detail in Figs. 4 and 5 and comprises two sheets of fibreboard l8 and I2 fastened together and in bent nested relation as by staples l4 and I8, and impregnated or coated with a. material such as asphalt 'or resin, which Waterproofs and hardens the surface. The exterior surface .of the impregnated sheet i8 is covered with a facing of a flexible sheet of asphalt-saturated felt l5 having an adherent surfacing of finely-divided mineral .matter divided into horizontal stripes to provide a plurality of brick and mortar appearing portions of contrasting color and spaced in similar relation to the spacing of the brick and mortar appearing courses of the siding strips 6. As shown in Figs. 4 and 5, longitudinal edge portions l6 and I! of the mineral covered asphalt-saturated felt are doubled around the longitudinal edges of the fibreboard sheet l8, and are fastened against the inside marginal portions thereof as'by staples l8. Additionally, if desired, suitable adhesive material, such as asphalt, may be interposed between the sheets l8 and I5 to attach the granule coated sheet more securely.

In order to permit the use of several units 8 in vertical series without sacrific of waterproofing qualities, I preferably form each corner unit in such manner that it is provided with oppositev ends tongued and grooved, respectively, and

adapted to complement and interfit with grooved and tongued ends, respectively, of adjacent units. For this purpose, I utilize a fibreboard sheet l0 and fibreboard sheet I2 of substantially equal length and of unequal width. As indicated in Fig.

2 3, these are stapled together with their ends in offset and stepped relation as indicated by Fig. 4,.

as by a row of rivets or staples l9 inserted substantially along the center line. The combined parts are then bent along the center line to the desired angle, as shown in Fig. 3a, and, after bending, additional staples H are inserted to maintain the composite flbreboard sheets in bent and nested relation. The combined sheets may then be waterproofed. Thereafter, as indicated by Fig. 4, in applying the outside mineral granule coated sheet IS, the sheet i5 is offset with relation to the ends of the flbreboard I so that one end of the element 8 will present an exposed tongue 20, being a portion of the flbreboard sheet Ill, and th other end of the element 8 will present a groove 22 formed between the felt sheet l on one side and the extending ends of the doubled back marginal portions I6 and ll of the sheet I5 together with the extending end 24 of the reinforcing inside fibreboard sheet l2, on the other side. At some stage in the operations, the comers of in application of the corner element 8 to the building structure, it may be applied evenly and flush against the relatively smooth surfaces afforded at the building corner by the siding strips 8, 6, the reinforcing member I! acting as a filler over the angled faces of sheet l0 between marginal portions l6 and I1. After the attachment of onecorner element 8, an adjacent element may" be fitted to it by the tongue and groove arrangements 20 and 22 to form a waterproof horizontal Joint between the adjacent corner elements 8, especially effective if asphalt is present on the entire exterior surface of the flbreboard M, including the tongue 20, as a result either of impregnation or of application as an adhesive for the attachment of the granule coated felt sheet l5.

Additionally, because of the flexible nature of the elements 8, comprised asthey are of fibreboard and asphalt-saturated felt, without the interposition of metallic reinforcement, the elements will readily conform with any building irregularities.

As shown in Fig. 1, the corner elements 8 are so positioned relative to the mortar and brick courses of the siding strips 6, that the brick-appearing construction will be carried around the comer of the building. Furthermore, because the vertical, longitudinal edges of the element I are mineral granule coated, the juncture of the corner element with the siding strip will not be unsightly, as the brick and mortar appearing courses of the siding strips will meet similar courses of the corner element along a single vertical line without intervening space.

While. the foregoing description has been confined to the cap sheet type of corner element,

i. e. with the asphalt-saturated felt sheet II, ,it

is to be understood that a similar corner element construction may be formed by afllxing directly to th exterior surface of the composite formed by the fibreboard sheets l0 and ii, a coating of asphalt with mineral granules embedded therein, and with or without bumed-in or branded mortar lines. In such cases, the doubled over portions l6 and ll of the cap sheet l5 shown in the drawings will of course not be present, but a ship-lapped joint between the elements will be provided. It is also to be understood that the construction is equally applicable for use in the formation of corner elements which have simulated masonry appearances other than that of brick and mortar, for instance those in which the appearance is one of stone or wood, or even shingles.

An essential similar type ofcorner element construction is illustrated by Fig. 9, but with the corner element being formed for use at an inside building corner. As there shown, the fibreboard sheets l0 and I! of Fig. 3 have been bent in a direction opposite to that in which they are bent in forming the element shown in Fig.

3a. Thereafter, the cap sheet I5 is affixed overthe exposed surface of the wide fibreboard shee't l0, and with the reinforcing fibreboard sheet I! extending over the outside angle of the corner element. As will be understood, the element is therefore adapted to be placed over the longitudinal joint between siding strips meeting at an inside comer of a building construction.

If desired, a longitudinal wooden strip Ila, having an outside 90 angle, may be affixed to the fibreboard base at the apex of the bend of Fig. 3a, before afflxing cap sheet IS, in order to provide a sharper corner, should it be found that the corner element angle is more rounded than desired.

I claim:

l. A flexible preformed buildin comer element comprising two substantially rectangular sheets faces in substantially the same planes as adiacent exposed surfaces of the narrower sheet, with the narrower sheet acting as a filler to support said element intermediate said doubled portions.

2. A performed building corner element as claimed in claim 1, in which said wider board and said felt sheet are assembled with their ends in stepped relation, with said felt sheet projecting' beyond said wider board at the same end thereof as said narrower board projects, to form a groove, and said felt sheet terminating short of said wider board at the end that the wider board projects beyond said narrower board to leave said wider board projecting to form a tongue for said element.
